Solar exported (kWh)

EV charging usage (kWh)

EV off-peak/free/discounted charging windows vary a lot by state and retailer (some plans offer a free midday "solar soak" window, others discount 12am–4am) — modelling the exact time-of-use split is out of scope here. Enter your best estimate of total EV-charging kWh for the period and the flat (or roughly off-peak) rate you were quoted per vendor below.
